Where Would You Recommend Using a Bin Activator?


A bin activator is a specific kind of bin discharger that shakes up materials sitting in a hopper or bin for too long. For instance, product loss or leaks can occur when powdery or granular materials create arcs and bridges, preventing them from flowing uniformly. Vibration is used in bin activators to rouse the contents and encourage movement. They can be set up independently at the bottom of a silo, bin, or hopper. A Vibrating feeder cone receives the material and consistently releases the powder into the next process stage. 

 

Bin Activators: When to Use Them

If your bulk product is sticky or doesn't respond well to compassion, you shouldn't use a vibrating bin activator. Furthermore, while bin activators are the most cost-effective technology for low discharge rates, their cost-effectiveness decreases as discharge rates increase.


In addition to the container, the bin activator will shake any attached equipment. If your bin or hopper needs to be better made and maintained, this could cause structural damage.


To maximize a bin activator's effectiveness, it must be set up, considering the downstream machinery. Decide if you want the vibration to be steady or cycle on and off before ordering a bin activator.


Please don't hesitate to contact the friendly engineers at Wrights Dowson Group. To ensure that your bin activators meet your precise production requirements, we can assist you in determining their specific parameters. 

 

Functions of a Bin Activator:

The engineering and manufacturing staff of Polimak offer a wide variety of bin activators, all made in factories and boast some novel design elements. Key features of the apparatus's design include the following:

 

Confetti Dish

A baffle plate with a tapered, conical profile is at the exact middle of the bin's activator's diameter. The baffle is securely fastened to the machine's frame with structural steel components. Applying vibrations directly to the bulk material helps the equipment upstream move the material more efficiently. By acting as a wedge beneath the bulk material, a secondary deflector plate eases the load on the bin activator's lower half and propels it around the areas adjacent to the cone's surface. 

 

Polymer suspensions and seals that were engineered:

A vibrating bin discharger is connected to the equipment mounted above it using special spring suspension links and a designed polymer seal. The leaking of the dry bulk material can be avoided if the polyurethane seal is properly designed and installed. Additionally, longevity and tolerance to extreme stress are assured. Vibrations from motors, changes in pressure, etc., all contribute to this strain.

 

Flange:

A silo's cone must be shorter than typical to accommodate a bin activator. Because of this, the outlet is very spacious. A flange is welded to the silo outlet (just above the outlet) and the bin activator at the factory. When being attached to the silo, the Vibrating screen bin discharger is bolted to the flange.

 

 Conclusion:

The cone-shaped bin activator relies on the principle of convergence to perform its function. When discharging from a bin into a feeder, container, or other downstream devices, the solid bulk material passes via an inlet with a greater diameter. It exits the chest through an outlet with a smaller diameter.

Importance of Rectangular and Circular vibrating screen

Screening medium to coarse-grained bulk materials (5.0 mm to 100 mm) is done by circular vibrating screens, also known as Circular vibrating screen. For circular vibrating screens to function, the screen mesh is indirectly excited. Unbalanced masses cause a circular vibrating motion in the entire screen frame.


Rectangular Vibrating Screen Characteristics

Rectangular vibrating screen come in various models and configurations to meet virtually every screening, dewatering, classification, or scalping need.

Stainless steel mesh, nylon or synthetic fabric, bar screen, or wedge wire dewatering panels are some other materials found in screens.

Screen fabric is chosen for longer durability and is set up for easy maintenance and replacement. Carbon steel, corrosion-resistant stainless steel, or another lined media can be used for Vibrating compaction table contact surfaces, depending on the quality of the screened bulk material.

Screen bodies can either be open, exposing the processed material or closed, preventing dust from escaping.

A cassette of bouncing balls can be arranged to lessen screen cloth choking caused by sticky materials.

 

Screeners that are either round or mechanical, or rectangular:

One of the three most common screener shapes is a rectangular shape. These machines are a great all-around option compared to circular screeners, which are more space-efficient but usually more expensive, and mechanical screeners, which are easier to use but less successful at fine-separating and sieving chores.

 

When deciding on a screener, it's important to think about the following:

Needs in Manufacturing: 

A good screener consistently and successfully separates or screens out the target material. To maximize productivity, you should invest in machines that can perform many functions.

Footprint: 

A compact machine has many advantages in crowded manufacturing facilities. However, smaller devices are limited in the material they can process simultaneously. A machine with a larger footprint could be preferable if production volumes are high.

Maintenance: 

Most screeners need help to function properly during maintenance, reducing your efficiency. If downtime is not an option, a machine with easily accessible parts and minimal moving parts may be the best buy.

Safety: 

Pharmaceutical and chemical manufacturing are only two examples of industries where screening for safety is a top priority. You can install ventilation hoods on many screeners to keep your team safe when working with potentially dangerous chemicals.

 

How to Use a Rectangular Vibrating Screen:

The screen frame vibrates straight or linearly because the motors are mounted at right angles. Because of this, larger particles are efficiently conveyed forward even when the screen's frame is tilted upward. The structure of the rectangular screen can be tilted downward at an angle that best suits the intended use. The machine's capacity is maximized in the uphill position, leading to a pool at the feed end. The water pressure in the pool causes the fluid to spread more. The large particles are efficiently transported by the screen frame's horizontal Vibrating table screens and released outside the pool area.


Conclusion:

Buying powder materials in bulk can save businesses a lot of money and boost output at powder processing facilities. However, powder processing companies must invest in a bulk bag unloader system to collect the product and dispense it into the processing line to take advantage of all this and more.
